General description
Potassium carbonate is an inorganic base. It participates as base in the palladacycle catalyzed Heck reaction of chlorobenzene with styrene.
Application
Potassium carbonate was used in the following studies:
- Synthesis of polysubstituted iodobenzene derivatives.
- As base for the synthesis of high molecular weight homopolymers and copolymers derived from various bisphenols.
- As base for the Suzuki coupling of aryl halides with aryl boronic acids.
- As base for the Heck reaction of styrene and bromobenzene.

The cobalt-catalyzed Diels-Alder reaction of trimethylsilyl-substituted alkynes with 1,3-dienes led to dihydroaromatic intermediates which were transformed into iodobenzene derivatives. For this transformation, the dihydroaromatic intermediates had to be oxidized and the trimethylsilyl-substituted arene had to undergo a silicon-iodine exchange reaction.
